An international supplier of a powdered hot-chocolate drink wanted to test several aspects of their packaging. The powder is packed in a plastic-capped, foil-sealed cardboard tube container.
The cardboard container is tested for its top-load strength (column crush) to make sure it can withstand the lid being applied in production. The pull-off force to separate the lid from the metal rim of the container is also measured. Finally, the peel strength to remove the induction-sealed foil closure is tested at an angle of 90 degrees, both in pre-production specimens and after being applied to the container.
To enable reliable and secure gripping of the packaging elements for the tension tests, Mecmesin designed a custom jig based around an assisted peel table. This ensured that forces were applied at the correct angle and samples were simple to insert & remove.
The client was then able to use their Mecmesin universal tester for all four tests, with quick and easy exchange of fixtures, allowing rapid throughput of samples for testing.

Adhesive test on capsulated cork stoppers
A capsulated stopper (T-top, Bar-Top or Altop) is a natural or synthetic cork stopper where the end is glued into a cap of wood, PVC, porcelain, metal, glass or other material. Testing the quality of the adhesive bond between cork and cap is a fundamental check performed by manufacturers of capsulated stoppers and their customers
Vial stopper needle penetrability residual seal force and torque testing
COVID-19 vaccines, as parenteral medications, enter the body by injection through the tissue and circulatory system. Testing the physical properties of these vital drug container systems is a key factor in quality-control testing
Hand sanitiser dispenser pump testing
Sales of antibacterial gels have soared enormously following National Health Service advice telling the public to thoroughly wash hands in order to stay protected from Coronavirus. In fact, even before the 2020 pandemic crisis, the presence of hand sanitisers had already become commonplace, not only in hospitals but also in schools, restaurants and offices.
Adhesion peel strength of COVID-19 tapes and stickers
In the wake of the Covid-19 lockdown, there have been clear guidelines issued to businesses on keeping staff and customers safe. These include wall signs encouraging people to follow hygiene guidelines through to purpose-made floor tape to help enforce social distancing rules. For successful long-lasting application to surfaces, they all rely on the stickiness provided by the humble self-adhesive.
Break-loose and sustaining force tests of pre-filled drug cartridges to ISO 11608-3
Mechanical pen injectors for delivering drugs, such as insulin, have found increasing acceptance over the traditional vial-and-syringe method. To validate new pen injector designs and maintain quality when they are mass-produced requires extensive testing.
Vaccine delivery device and packaging testing
As COVID-19 has rapidly spread around the world, there is a concerted global effort to find a vaccine. Whether administered via an oral, subcutaneous, intramuscular, intradermal, or intranasal route, vaccines need to be administered via a medical device, and these must be tested to esnure they are safe and meet stringent standards and regulations
PET preforms - repurposing production for COVID-19 test kits
PET preforms are typically blow-moulded to create the ubiquitous plastic bottles containing carbonated and still beverages. The production process to fill and seal these bottles with a screw-cap is a demanding one, so a number of tests are performed to ensure quality control specifications are met for this core packaging.
Probiotic drink packaging testing
As demand for dietary supplements continues to surge, immune-boosting products, such as prebiotics and probiotics, are amongst the most popular. Getting these liquid probiotic products noticed by the consumer relies on eye-catching innovative packaging which must be easy-to-open and reseal whilst remaining economic to use for the beverage producer.
Testing Ventilator and Breathing Assistance Apparatus Components
A ventilator (respirator) provides ‘mechanical ventilation’ by moving breathable air into and out of the lungs of patients unable to breathe sufficiently well unaided. Such fundamental hospital equipment is essential for all patient care where assisted breathing is necessary.
Face mask strength testing
Manufacturing masks is not as easy as you might imagine. International test standards exist to make sure the face masks can be verified to protect clinicians and patients from pathogens spread by blood, body fluids and secretions and now to limit the spread of COVID-19 coronavirus.
Pharmaceutical tablet crush and break strength
Many products come in tablet form, with a durability designed for both packaging and for use. Too brittle or too hard, and they may not be fit for use, or at best perform below expectation. The only way to determine consistency is mechanical testing of samples.
Lipstick tube force and torque testing
Testing the mechanical performance of the lipstick tube is a crucial part of the quality-control process for cosmetics manufacturers. Leading players in the cosmetics industry have come to rely on Mecmesin’s range of affordable force and torque testers to carry out checks on batches of lipsticks produced.
Mecmesin's materials testers
Testing the physical strength properties of materials, in accordance with international or in-house standards, is a key part of determining their characteristics to better understand the effects of process improvements. With this in mind, Mecmesin has designed a range of static-load Materials Testers powered by intuitive VectorPro MT software.
Top-load crush of plastic bottle with semi-automated test process
To guarantee their containers would perform as expected along customer production lines and remain intact during transportation and storage, US company, Silgan Plastics wanted to undertake top-load tests according to internal, customer and Supplier Packaging Information (SPI) standards.
Dispensing pump assembly testing
Mecmesin's customer manufactures a range of dispensing pumps for the cosmetic and beauty-care industry. A requirement was identified to measure the actuation force of the pump assembly and the pull-off force of the pump handle. The VersaTest motorised test stand was chosen as it gave the necessary repeatability and consistency independent of operator, which a manual stand could not.
